I am planning for a 400 gallon native species aquarium for the shop I work at.

The tank will be exposed to sunlight and it is my intension to have one engineered that will have a constant current cycling through it. It is to represent the Mississippi River and the species that the Balde Eagle has had in its natural ecosystem for the millenias prior to european settlement.

I am curious as to if any of you have suggestions for me to consider in design and species of fish to try to obtain for the tank. Further, will I need to farm my own food for the tank? I want this to be as sustainable and natural as possible with limited feeding behaviors imprinted on my fishes.

I know its a few questions balled in one and thank you in advance for your input.

My start on a species wish list is;

Gizzard Shad
Shovelnose Sturgeon
Northern Hogsucker
Blue Sucker
Paddle Fish
Mooneye
Goldeye
Paddle Fish
Mooneye
Goldeye
Quillback Carpsucker
Spotted Sucker
Golden Redhorse
River Redhorse
Greater Redhorse
Warmouth
Silver Shiner

I am also curious as to how I should be thinking about the predator species as they will need to be somehow integrated in the mini ecosystem.

thanks again!
